About
Store description and overview from Steam.
A baseball management sim modeled on Japan's pro baseball (NPB) — no action, pure front office.
Run the draft, free agency, trades, contract talks, scouting and stadium finances, then simulate a season instantly or watch it unfold pitch by pitch, stepping in to call the shots at any at-bat.
Set league count, team count and season length however you like — from a 12-team Japanese-style league up to 30 clubs across 6 leagues. Edit every player, team and ballpark with the bundled CSV editor, and build a league that's entirely your own.
Detailed per-player ratings and a custom engine resolve each game one pitch at a time. Watch it play out on full auto, or step in and call the shots at any at-bat.
Draft, free agency, trades, contract talks, scouting. Multi-stage salary negotiations, multi-year deals with buyouts, retirement talks — every front-office decision is here.
The same prospect, seen through different scouting. (Top = poorly scouted / Bottom = thoroughly scouted)
Ratings are shown with observation error — you never know a player's true ability until they take the field. The more you invest in scouting, the more the fog lifts.
Ticket pricing, sponsorships and stadium renovations keep the money moving. How do you build a winner on a limited budget?
From a 12-team Japanese-style league up to 30 clubs across 6 leagues — configure it however you like. Players, teams and ballparks are editable via the bundled CSV editor, and sound effects and stadium images can be swapped too (MOD support).
Aging, generational change, retirements — and all-time records piling up. Season after season, a whole world takes shape.
Japanese, English, Korean and Traditional Chinese.
From the developer
Built by a solo developer. The features I set out to make are all in — this launches as a complete game. I'll keep updating it after release, at a steady solo pace, based on your feedback.
